1. Introduction
The Digitus HDMI KVM extender set consists of a sender unit
(local location) as well as a receiver unit (remote location). The

6, 5e, 5) up to a maximum distance of 120m. The HDMI signal
can also be extended to an unlimited distance via the existing
network infrastructure (via IP connection). The highest
